Fresh squeezed juice in general will have more nutritional value than store bought juice, simply because of less oxidation over time. Air destroys a number of nutrients over time, especially vitamin C, and store bought juice is often exposed to air during production/storage etc before it gets packaged.

As far as juice only diets, you'd be missing a lot of things in your diet, not the least of which is fiber. You can't do that for long....

LOL!
As I was reading the thread title, I was thinking I should answer with "Hell yes, here's what I use:"

As far as self-made juice: it's definitely more tasty, but a lot more effort. Not worth it for me, right now.

Re. juice replacing a meal: the banana juice that my kids are fond of almost works as a full meal. 15g carbs/ 100ml - jeez.

Oh, and anyone throwing around the term "detox" should be required to go into specifics - what toxins, how do you get rid of them, how can you tell you've succeeded? As Wikipedia states
( http://en.wikipedia.org/wiki/Detoxification )

Certain approaches in alternative medicine claim to remove "toxins" from the body through herbal, electrical or electromagnetic treatments (such as the Aqua Detox treatment). These toxins are undefined and have no scientific basis,[5] making the validity of such techniques questionable.

Reason: added some substance

There are no wrong threats, only wrong answers. (Strategy game truism)

I'm considering it more as a supplement rather than an all out meal replacement, personally. I have frequently wondered if I was getting the right vitamins and nutrients. This looks like a good source for what I may be missing with out having to take more pills.

I like to juice just to give me something to drink that's not carbonated, containing alcohol, processed sugars, or other crap. I just like the taste and find it refreshing not to mention I figure it's the easiest way to consume large amounts of spinach, kale, carrot, and whatever other veggies in a short time.
